Terramaster T6-423 Thermals

[Enquiries]

Hey, thanks for offering this free service. I am pretty far along in my selection process but I am happy to hear suggestions/criticism from experienced builders. My plan is based on a T6-423 populated with 10 TB HGST He10 (ex-datacenter, 25KH operating time, 5yr warranty) which are less than $90, and budget for two spares. This should yield a bit under 40 TB in RAID 6/Z2. I bought one to investigate and the drive was in superb condition.

Your review was excellent but did not cover thermal performance or noise levels. I intend to run this in a large bedroom closet so drive and fan noise is not a big problem. Can you tell me the approx temperature range I should expect and what you think is permissible when all 6 bays are used? Should I consider replacing the fans?

I thought about a DS620Slim with 6x 4 TB SSDs, but it's hard to justify with only 1Gbe, and nvme boxes due soon. Thx

Your plan of using a T6-423 populated with 10 TB HGST He10 drives in RAID 6/Z2 is a good one, as these drives have a good reputation for reliability and are available at a reasonable price. Having two spares on hand is also a smart move, as it will allow you to quickly replace any failed drives and maintain data integrity.

In terms of thermal performance, the T6-423 has a built-in 120mm rear fan that should provide adequate cooling for the drives, even when all six bays are in use. However, the exact temperature range you should expect will depend on the ambient temperature of the room where the NAS is located, as well as other factors such as the load on the drives and the amount of ventilation in the closet. Generally, you should aim to keep the drives at or below 50-55 degrees Celsius to ensure long-term reliability.

As for noise levels, the T6-423 is designed to be relatively quiet, with a noise level of around 25 dB(A) when the drives are idle. However, when the drives are under load, the noise level will increase somewhat. If noise is not a big concern for you, then you should be fine with the stock fans. However, if you want to reduce noise further, you could consider replacing the fans with quieter models.

Regarding the DS620Slim, while it has the advantage of using SSDs, the limited 1Gbe network interface would likely bottleneck performance when transferring large files or streaming media to multiple devices.
